Notes

How to Store & Reheat Crock Pot Mac and Cheese

Allow the mac and cheese to cool to room temp. This will keep it from sweating in your storage and making it soggy. Once it's cooled, transfer the mac and cheese to an airtight container.
I personally like to store the breadcrumb topping separately from the cheesy pasta. If you know from jump that you will probably have leftovers, I suggest adding that topping just to the amount you will be serving. Store the rest so it stays crunchy.
Reheat leftovers in the oven at 350°F (175°C). Place the mac and cheese in an oven-safe dish. If you've stored the breadcrumb topping separately, sprinkle it on top now. Cover with aluminum foil to prevent the top from burning and to help retain moisture. Cook for 15-20 minutes, or until heated through and the breadcrumb topping is crispy again.
If the breadcrumb topping isn’t crispy, you can remove the foil and broil for an additional 1-2 minutes. Watch closely so you don't let it burn up!
How long will crock pot mac and cheese last in the fridge?
About 3 days.
Can I freeze slow cooker mac and cheese?
No, I don't recommend freezing this boos. Dairy often breaks when it's frozen so when you thaw it out again the cheese sauce can be a bit grainy instead of creamy. Also, the pasta will often thaw out with a much softer texture.
